Perhaps because the computer I used to create the USB runs El Capitan, while MBA came with Lion. Using USB on MBA at boot up leads to the regular boot up progress bar going about halfway, then stopping at an error screen (box with an "X" inside).
Last thing I tried: Recovery Disk Assistant on my working Macbook Pro to create recovery USB. Not 100% sure why, since I didn't erase it, but given that I got the MBA from someone else as well, it is possible that partition was erased earlier. Please try again later."Ĭhecking Disk Utility, I see there's no recovery partition.

I have now been trying to re-install OS X on the MBA, but didn't succeed. Before doing so, I erased the default system/home partition with Disk Utility in Recovery Mode. The machine came with OS X Lion pre-installed, and has been upgraded up to El Capitan while I used it. I'm trying to reinstall OS X (Lion, or higher - which version doesn't matter to me right now) on a Macbook Air, 11-inch, Late 2010 model. Hoping someone here has a different idea. Tried every suggestion I could find on the net, but nothing worked.
